Wisconsin quadruple murder suspect found dead

Tyrone Adair, the subject of a massive manhunt after his two daughters and their mothers were found murdered last Thursday, was found dead Monday by police in Cottage Grove, Wis., in the car owned by one of the women killed. They say he had a gunshot wound, and an autopsy will be performed on the 38-year-old man today. But until the results are in, police are not saying whether Adair killed himself.

Police found two guns in the car, and it appears that one of them may be the murder weapon in one of the cases, the Wisconsin State Journal reported. Adair was not allowed to own a firearm because he was under an active restraining order involving a third woman, but it appears he bought one anyway, from Craigslist.

Police say that Adair was suspected of killing his girlfriend Tracy Judd, 33, and their 23-month-old daughter, Deja, as well as Amber Weigel, 25, and their daughter Neveah Weigel-Adair, 2, on Thursday. Madison police found Judd and Deja dead in the trunk of Adair's car. Weigel's boyfriend, Jon Butler, found her and her daughter dead the garage of the home the three shared.
